For the hot end, an aluminium mount was pressed into soil, transferring the Earth’s ambient heat to the engine’s bottom plate ...

The model Stirling engine is a staple of novelty catalogues, and we daresay that were it not for their high price there might be more than one Hackaday reader or writer who might own one. All is not ...

This engine doesn’t power anything in particular except our deeper understanding of thermodynamics as well microscopic ...

Instead of absorbing energy from the sun to produce electricity, a new class of devices generates power by absorbing heat ...

The smaller the better, and in a world of fast-developing technology, that’s called innovation. Just this month, a desk-sized turbine capable of powering a small town was announced to be under ...

The heat engine works as its intrinsic spin converts heat absorbed from laser beams into oscillations of a trapped ion. Credit: John Goold, Trinity College Dublin A new heat engine made from a ...

Just how small can you make an engine? Two researchers from the University of Stuttgart and the Max Planck Institute for Intelligent Systems, Valentin Blickle and Clemens Bechinger, successfully ...

Research from The University of Manchester has thrown new light on the use of miniaturised ‘heat engines’ that could one day help power nanoscale machines like quantum computers. Heat engines are ...
